| Research Abstract |
In order to fill in the observation gap in the equatorial region, SG (Superconducting Gravimeter) observations have been newly started in Cibinong, Indonesia. The result of the Earth tide analysis showed good correspondence with that of Bandung, which had been the unique one in equatorial region so far. In addition, the advantages of the recent ocean tide models, the relation between the long period gravity changes and the groundwater level changes have been confirmed. As for the Earth's free oscilla-tions, the 2011 Tohoku Earthquake (Mw9.0) have been successfully recorded. The data should be expected to contribute to several analyses in the future.
